Equivalent Elastic Constants of Truss Core Sandwich Plates
(The American Society of Mechanical Engineers (ASME), 2011)A plate structure of a triangular truss core sandwiched by two panels is treated as an equivalent homogeneous laminated plate by obtaining equivalent anisotropic elastic constants. The equivalent ... -
Vibration Reduction of a Floating Roof by Dynamic Vibration Absorbers
(The American Society of Mechanical Engineers (ASME), 2011)This paper investigates the use of dynamic vibration absorbers as a means to reduce the vibration of a floating roof due to sloshing caused by long-period earthquakes. It is shown that the ... -
Failure Bending Moment for Pipes With an Arbitrary-Shaped Circumferential Flaw
(The American Society of Mechanical Engineers (ASME), 2011)When a flaw is detected in a stainless steel piping system, an evaluation has to be performed to determine its suitability for continued operation. The failure bending moment of the flawed ... -
Analysis of the Dynamic Response of a Controlled Detonation Chamber
(The American Society of Mechanical Engineers (ASME), 2011)Detonation chambers (either mobile or fixed) are used worldwide for a wide range of applications. At present, a 1/7 scale model of a 1 ton detonation chamber is available for extended testing ... -
Liquid Leak Predictions in Micro- and Nanoporous Gaskets
(The American Society of Mechanical Engineers (ASME), 2011)In recent years, quite few experimental and theoretical studies have been conducted to predict gas leak rate through gaskets. However, a very limited work is done on liquid leak rates through ... -
Shakedown Limit Load Determination for a Kinematically Hardening 90 deg Pipe Bend Subjected to Steady Internal Pressures and Cyclic Bending Moments
(The American Society of Mechanical Engineers (ASME), 2011)A simplified technique for determining the lower bound shakedown limit load of a structure, employing an elastic–perfectly plastic (EPP) material model, was previously developed and successfully ... -
Stress Intensity Factor Equations for Internal Semi-Elliptical Cracks in Pressurized Cylinders
(The American Society of Mechanical Engineers (ASME), 2011)In order to calculate the fatigue life of cylinders subjected to internal pressure using the fracture mechanics approach, the stress intensity factors (SIFs) for internal semi-elliptical cracks ... -
Plastic Instabilities in Spherical Vessels for Static and Dynamic Loading
(The American Society of Mechanical Engineers (ASME), 2011)Significant changes were made in design limits for pressurized vessels in the 2007 version of the ASME code (Sec. VIII, Div. 3) and 2008 and 2009 Addenda, and these are now a part of the ... -
Residual Stresses in Roller Expanded Tube-Tubesheet Joints With Large Initial Clearance and Grooves
(The American Society of Mechanical Engineers (ASME), 2011)Heat exchanger tube rolling introduces tensile residual stresses in the expanded part of the tube and the transition zone between the expanded and unexpanded regions of the tube. These tensile ... -
Formation Mechanism of the Eigen-line in Electrofusion Joints of Polyethylene Pipes
(The American Society of Mechanical Engineers (ASME), 2011)Cold welding is the most dangerous defect in the electrofusion joint of polyethylene (PE) pipes. A proprietary method was developed to detect the degree of cold welding by using an Eigen-line, ... -
